PAPER-GUIDING DEVICE FOR TYPE-WRITING MACHINES.

Specification of Letters Patent.

Application filed March 11,1914. smalm. 823,914.

To all whom it may concern Be it known that we, HARRY TawIN CnoMER' and CLAYTON C. HARTING, citizens of the United States, and residents, respectively, of Oak Park, in the coun'ty of Cook and State of Illinois, and of Woodstock, 1n the county of McHenry and State of 1111- nois, have invented certain new and useful Improvements .in Paper-Guiding Devices for Type-Writing Machines; and we do hereby declare that the followmg 1s a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of th1s specification.

This invention relates to that class of paper-guiding mechanism for typewriting machines in which paper-guiding fingers or arms upon the carriage frame are employed for guiding the paper to be operatedupon.

The principal object of the inventlon is to provide a simple, economical and efliclent paper-guiding mechanism for typewriting machines.

Other and further objects of the invention will appear from an examination of the specification and from an inspection of the accompanying drawings which are made a part hereof.

The invention consists of certain features of construction, combinations, and arrangements of parts, all of which will be fully set forth and described herein and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a paper carriage of a typewriting machine, provided with paperguiding mechanism constructed in accordance with our invention and improvements; and Fig. 2, a vertical sectional view, taken on line 2 of Fig. 1 looking in the direction of the arrow.

In constructing a paper carriage for a typewriting machine provided with paperguiding mechanism made in accordance with our invention and improvements, a carriage frame a is provided having end frame memhers I) in which a supporting platen 0 is rotatively mounted in suitable bearings d. The end frame members b are connected by means of rods or transverse frame members e, f, and by means of a toothed-rack bar g,

which extends from one to the other of said frame members and is provided with teeth h, 71 adapted to be engaged by the esc'apement mechanism or escapement and tabulating mechanism of the typewriting machine.

Paper-guiding plates or shields Z, m are mounted in the carriage frame-back of the apron and rollers for engaging and guid ing the portion of the paper which partly encircles the platen and is located between the main paper-guiding plate or shield Z and the space bar or scale plate at, or

in position to be fed around with the rotative platen in the direction of the printing line, may be of any desired or ordinary and well known form, and may comprise the ordinary well known parts of a paper-feeding mechanism of any desired form of typewriting machine.

'60 platen c and provided with a space therebe- In the accompanying drawings is shown a paper carriage of an Oliver typewriting machine, or such parts of thecarriage as'are deemed necessary in order to enable the invention to be understood, made and used.

A paper carriage, of .the form shown in the drawings, comprises paper-guiding and supporting rolls 0, p and each arranged inparallel relation to the platen and journaled in suitable bearings in the carriage frame or in the paper-guiding and supporting apron mechanism for thepaper carriage. These paper-guiding or feeding rolls are located adjacent to the periphery of the platen and intermediate the main back paper-guiding plate or shield Z and the scale bar or plate. A paper-guiding plate 1' located intermediate the rolls 0 and p and-a curved paper-guiding plate 8 located between the rolls 3) and g serve to guide the paper as it passes between the rolls 0, p and g or paper-guiding apron and the platen; The usual means for releasing the paper is provided, comprising a rocking shaft or bar It and means for operating and operatively connecting the same with the apron or supporting mechanism for the rolls 0, p and 9, so as to enable the pressure upon the paper to bereleascd as desired by swinging said paper-feeding rolls away from the platen, or permitting them to be yieldingly pressed toward the platen and into operative engagement with the paper by means of spring mechanism'not shown.

Itisverydesirablethatpaper-guidmgmechanism of an improved characterbe provided for guiding and retaining in pos1t1 on the portion of the paper which is at the printing hne, and that portion of the paper which after passing the printing line is to be guided and supported in position to be visible. The

construction of the paper-guiding mechanism should be such as to cover or obscure as little as possible of the surface of the paper-which is of varying widths-so that the impression of the characters will be uniform and may be read with facility and without the necessity of moving the paper or any of the parts of the carriage, or paperguiding mechanism, no matter how narrow or how wide the paper operated upon may be. In order to provide means whereby this and other objects of the invention may be accomplished in an eificient manner, a narrow guide-rod, bar or wire 25 is mounted,

by preference, in fixed relation to the car-V riage frame with its opposite ends to secured to the end frame members I) of the carriage and located adjacent to the perlpheral portion of the platen. This rod forms oblique paper-guiding arms '0 which extend from the opposite ends of the platen and from the end frame members 6 of the carriage close to the periphery of the platen and obliquely toward the cnter of the carriage frame and paper, in the direction of the movement of the paper. The arms are thus oblique with respect to the paper and the direction of movement of the paper to be engaged and guided thereby, and are so disposed that the paper is engaged progressively first at or near its outer marginal portions and progressively toward the longitudinal center of the sheet or sheets. These oblique arms are adapted to extend across and in oblique guiding engagement with sheets of varying Widths without adjustment, and are at all times in position to engage and guide sheets of any desired width which the carriage and platen will accommodate and retain them in position to render the printin visible. The

insane or angular in cross-section. and the clip is corresponding shape adapted to enable the clip to be fitted upon the rod in position to encircle and connect the rods 1. and 6. Flexible curved paper-guiding fingers or metallic strips 2 are adjustably mounted upon the carriage in position. to extend on the outside of the scale bar or plate n and between the oblique guide arms 0 and the platen and in the direction of movement of the paper, preferably beyond the inner or converging extremities of the oblique guide arms o and into position to be adjustably supported by the rod or bar 6. These adjustable paper-guiding fingers 2, when constructed as shown in the drawings, are in the form bf curved metallic strips and are each slidably mounted, at or near one end, upon the square or angular rod e, so as to extend between the oblique arm portions 41 and the platentheir forward or opposite ends 4 being, by preference, in sliding engagement with the outer surface of the scale bar or plate n, which, when arranged as shown, extends between the ends 4 of the adjustable fingers 2 and the platen. The scale bar or plate 11 is flexibly supported by means of supporting members 5 which have suitable notches or apertures into which the opposite ends 6 of the scale bar extend, so as to provide a pivotal or flexible support for the scale bar or plate adapted to enable the plate and the flexible guiding strips or fingers 2 to yieldingly engage the paper interposed between said guiding members and the platen. The guiding fingers and scale bar or plate are thus adapted to yield so as to admit and properly guide sheets of paper, which may vary in number.

The adjustable paper-guiding fingers 2, when arranged as above described, are adapted to be readily moved longitudinally of the platen and of the rod e, upon which they are slidably supported, and between the guiding arms a; and the platen, to any desired adjusted position, as required by reason of the various widths of paper to be operated upon, and are adapted to form marginal guides for paper which may vary in width from that of an ordinary postage stamp or even less to sheets of the maximum width adapted to be admitted through the paper carriage frame or properly supported by the platen.

The guiding arms '0 being in fixed relation to the carriage frame, and the guiding fingers 2 being adjustable with respect to the oblique guiding arms, as described and shown, it will be readily apparent that only the fingers 2 are required to be adjusted when relatively narrow strips or sheets of paper are to be printed or operated upon, and that the adjustment of the oblique arms is dispensed with and is unnecessary. The

provided with an opening therethrough of" surfaces of such relatively narrow strips or sheets are thus left uncovered and unobscured by any portion of the oblique arms not already in position and not required forthe proper guiding of such relatively narrow strips or sheets. The entire portions ofthe oblique arms located outside of the adjustable guiding fingers being not required for guiding strips or sheets so narrow as to require the inward adjustment of the adjustable fingers to positions between the extremities of the oblique guiding arms, those outer portions of the oblique arms required only for relatively wide sheets are allowed to remain outside of the adjustable fingers where they will not cover or obscure the.

printed matter or relatively narrow printed sheets.
